Die internationale Diskussion der letzten Jahrzehnte hat zur Frage nach einer effizienten Gestaltung der Einkommenssicherung von Arbeitslosen eine Reihe von Vorschlägen hervorgebracht, wie die von Beenstock/Brasse, Feldstein /Altman, Grubel und Orzag/Snower. Sie werden dargestellt und bewertet....

The paper generalizes the natural projection approach introduced by Balasko (1988) for the study of the qualitative equilibrium structure of exchange economies to a two period private ownership production model with uncertainty. It shows that long run equilibrium properties of the production...

We provide a microfounded account of imperfect information in a dynamic general equilibrium model by describing heterogeneous households that acquire information only through their participation in markets. Thus incomplete markets will imply incomplete information. We solve the model taking full...

The paper analyzes the effects of a source-based capital income tax on production and market structures, trade and capital flows as well as national and global welfare. The analysis is carried by means of a general equilibrium model of trade which incorporates international capital flows as well...

A general theoretical and empirical framework is developed for assessing the potential of a vertically integrated firm to foreclose downstream competitors. Using this framework a policymaker may also evaluate the empirical welfare effects from a vertically integrated firm raising rivals' costs....

We present a model in which investors observe the same macroeconomic data but have varying levels of information about the parameters that determine the distribution of the expected returns on investment. During a crisis that increases macroeconomic uncertainty and reduces asset prices, the...

Although an extensive amount of literature reviews emerging patterns of east-west co-operation, it is not easy to grasp the state of the art. Too many of the books, articles and papers tend to mark the trees rather than to map the forest. The paper analyses recent trends from the point of view...
